Cathodic Protection is Very Simply

The use of direct current electricity an external source to oppose the discharge of corrosion current from anodic areas that would be present naturally When a cathodic protection system is installed for maximum effect, all portions of the protected structure collect current from the surrounding electrolyte and the entrie exposed surface becomes a single cathodic area - hence the name.

Galvanizing has a historical background of use in reducing corrosion on pipelines Galvanizing is in effect a cathodic protection system utiling zinc as a sacrificial anode material dispersed on the surface of the pipe.

A well coated pipeline i.e., tape wrapped, no doubt will be have some coating defects or holidays. A cathodic protection system meet only protect the minute areas of steel exposed to the earth at the holidays rather than the whole surface of an uncoated structure may be thousands of time greather than the energy required to protect the same structure when well coated.
